SWITCH-STAND Specification of Letters Patent.

Patented Dec. 8, 1908.

Application filed January 8, 1908. Serial No. 409,836

T 0 all whom it may concern:

Be it known that we, JAMES FRANKLIN GURLEY and WILSON EDGAR LEWIS,citizens of the United States, residing at Raleigh, in the county ofWake and State of North Carolina, have invented a new and usefulSwitch-Stand, of which the following is a specification.

This invention relates generally to switch stands, and more particularlyto that class wherein there is a cage provided into which a switchmanhas to enter and lock himself in in the act of opening a switch to allowa train to pass upon the siding.

The object of the present invention is to improve and simplify theconstruction of such appliances and to render them more certain ofaction and less liable to become deranged in use.

With the above and other objects in view, as will appear as the natureof the invention is better understood, the same consists in the novelconstruction and combination of parts of a switch stand as will behereinafter fully described and claimed.

In the accompanying drawings forming a part of this specification and inwhich like characters of reference indicate corresponding parts,Figure 1is a view in side elevation, partly in section, of a switch standconstructed in accordance with the resent invention. Fig. 2 is ahorizonta sectional view taken on the line 2-2 of Fig. 1, and

displaying the position of the parts when the switch is closed. Fig. 3is a similar view showing the position of the parts when the switch isopen. Fig. 4 is a detail view of a portion of the operating mechanism.

Referring to the drawings, 1 designates a base of any suitable materialwhich is supported adjacent to the tracks T. Upon this base is mounted acage which is preferably circular in plan, and is composed of properlyspaced iron bars that are secured at their lower ends in a band 2secured to the base, and at their upper ends in a roof or cover 3. Onone side of the cage is left a s ace 4 forming a doorway, the sides ofwhic are formed by bars 5.

The doorway is adapted to be closed by a segmental door which consistsof two castings 6 that are carried by a shaft 7 that extends through thebase 1 at its lower end and above the roof 3 at its upper end, andcarries a semaphore or signal 8 of the usual or any preferredconstruction. The two segments l of the door are connected by bars 9which, when the arts are in the position shown in Fig. 3, WllFPOSitiTElYprevent egress through the doorway, this being the position that thedoor will occupy so long as the switch is The shaft 7 is stayed andbraced by a stand ard 10 that is bolted to the base and carries a curvedarm or support ll upon which is bolted two stops 12 that are undercut,as shown in Fig. 1, to receive the switch lever 13 and each stop isprovided with an orifice 14 to receive a pin 15 by which the switchlever may be locked in either of its adjusted positions.

In order to render the door easy of o eration, the lower segment carriesa sha t 16 upon which is mounted a wheel 17 adapted to traverse a track18 secured to the base.

The means for effecting the adjustment of the switch tracks S consistsof a trammel 18 that is secured to the lower end of the shaft andcarries two slide blocks 19 that are bolted at 20 to a lever 21, theouter end of which is secured at 22 to a bar 23 that connects the switchtongues S.

So long as the main line M is open, the door 6 will occupy the positionshown in Fig. 2, but should it be desired to open the switch for thepurpose of allowing a train to enter a siding, the operator opens thedoor 4 grasps the lever 13 and throws it from the position. shown inFig. 2 to that shown in Fig. 3, whereupon the switch tongues will beactuated through the tramniel and lever and be shifted to the positionshown in Fig. 3, thereby opening the switch. In this act the door ismoved opposite the doorway 4 so that egress therefrom is impossiblewithout first throwing the switch lever to the position shown in Fig. 2,whereupon the doorway will be opened.

It will be noted by reference to Fig. 3 that the door is considerablygreater in length than the width of the doorway and this arrangement isadopted in order to render it impossible for the switchman to partlyclose the switch and then leave the cage as the length of the door willprevent this, as by the time the door is fully 0 on the switch will havebeen entirely closcdi The advantages arising from the use of thetraminel with the switch tongue operating means is that it dispenseswith the employment of gears, which are objectionable owing to the factthat they become rusted and thus tit) diliieult to 0 )crate. By theemployment of the trammel greater ease of action at all times will besecured as there will be no such close fitting between the slide blocksand the 'uides as will at any time cause the parts to become rustlocked.

What is claimed is 1. I11 a switch stand, a cage having a doorway, asegmental door shiftable with relation to the doorway, a shaft uponwhich. the door is supported, a tramn'iel carried by the shaft, switchtongues, and a connection between the tranmiel and the switch tongues.

In a switch stand, a cage provided with a doorway, a shaft disposedwithin the cage and extending above and below the same, an

arm secured to the base of the cage through which the shaft rejects, ashifting lever secured t0 the she t and arranged to traverse the arm, atrammel carried by the shaft,

switch tongues, and a connection between the trammel and the switchtongues.

3. A switch stand comprising a cage provided with a doorway, a segmentalcage-like door for opening and closing the doorway, a roller forsupporting the door out of contact with the base of the cage, a shaft towhich the door is secured, a switch lever secured to the shaft, atrannnel secured to the lower end of the shaft exteriorly of the cage,switch 30 tongues, and a connection between the trammel and switchtongues.

In tcstii'nony that we claim the foregoing as our own, we have heretoaffixed our signa tures in the presence of two witnesses.
